カテプシンKタンパク分解触媒活性の測定

本アッセイでは、384ウェルプレートフォーマットにおいて、バキュロウイルス発現ヒトカテプシンSおよびBachemから入手可能なboc−Val−Leu−Lys−AMC蛍光基質を用い、それによって7つの試験化合物を既知のカテプシンS阻害剤コンパレータを含む陽性対照と同時に試験することができる。
12.5% DMSO(280μl/ウェル)を96深ウェルポリプロピレンプレートの2つの縦列の横列B〜Hに加える。基質(70μl/ウェル)を横列Aに加える。2×250μl/ウェルのアッセイ緩衝液(100mMリン酸ナトリウム、100mM NaCl、pH6.5)を横列Aに加え、混合し、プレートの横列Hまで2倍希釈する。
アッセイ緩衝液(100μl/ウェル)を96ウェルV底ポリプロピレンプレートの縦列2〜5および7〜12の横列4つに加える。アッセイ緩衝液(200μl/ウェル)を縦列1および6に加える。
上記方法を、以下の修正を施して、カテプシンLのKiを決定するのに用いる。
潜在的阻害剤を種々の濃度の試験化合物を用いて、上記アッセイによりスクリーニングする。反応は、基質と阻害剤の緩衝溶液に酵素を加えることにより開始した。Ki値を方程式1:
に従って計算した。
A:50ナノモル未満
B:50〜500ナノモル
C:501〜1000ナノモル
D:1001〜5000ナノモル
E:5001〜10000ナノモル
F:10000ナノモルを超える
本発明の化合物および示された比較の実施例について、その代謝安定性をサイトゾルアッセイで試験し、すなわち;それらの化合物を市販品として入手可能なヒト肝臓のサイトゾルフラクションでインキュベートし、化合物の消失をHPLCまたはLC/MSによってモニターした。プールされたヒト肝臓のサイトゾルフラクションは、単一個体からの血液と比べて異常値を示すことが少なく、また全血と異なり冷凍貯蔵できる。したがって、サイトゾルアッセイは、インビボ環境(例えば、全血にさらされた場合)における化合物の安定性への指標として試験される、一貫したアッセイを提供する。
この実施例では、ヒト消化管細胞を通過する阻害剤の輸送を測定する。アッセイでは、よく知られたCaco−2細胞を、40〜60の通過数で用いる。
一般に、すべての化合物は2〜4ウェルで試験する。側底および先端ウェルはそれぞれ1.5mLおよび0.4mL輸送緩衝液(TB)を含み、試験物質の標準濃度は10μMである。さらに、すべての試験溶液および緩衝液は1%DMSOを含む。試験前に、輸送プレートを10%血清が含まれる培養液で30分間プレコート(pre−coat)することによって、プラスチック物質への非特異的結合を回避する。21〜28日後、フィルター支持体上の培養細胞は浸透性試験の準備が整っている。
一般に、すべての化合物は2〜4ウェルで試験する。側底および先端ウェルは、それぞれ1.55mLおよび0.4mLのTBを含み、試験物質の標準濃度は10μMである。さらに、全ての試験溶液および緩衝液は1%DMSOを含む。試験前に、輸送プレートを10%血清が含まれる培養液で30分プレコートすることによって、プラスチック物質への非特異的結合を回避する。
